Specification of Letters Patent.

rat-@atea Fei. as, 1911.

Application filed May 7, 1910. Serial No. 559,950.

To all whom it may concern:

Be it known that I, VALTER F. FAIR- cLo'rir, a citizen of the United States, residing at Sprague, in the county of Montgomery and State of Alabama, hav-e invented certain new and useful Improvements in Plow-Beams, of which the following is a specification, reference being had to the accoml'ianying drawings.

This invention is an improved castmetal hollow plow beam comprising a top, sides, a bottom, and a, closed front end the bottom having an opening` extending nearly from end to end thereof, the top of the beam being formed at a suitable distance from its rear end with a series of transverse rack teeth, the sides of the, beam being formed at a. point between the rack teeth and the rear end of the beam, with inclined grooves to receive the lower ends of the handle bars, the integral rear portion of the bottom of the beam connecting the sides of the beam at the point where the said grooves are located, and strengthening the said grooved portion of the beam, the integral front portion of the bottom of the beam coacting with the wall which closes the front end of the beam to strengthen the construction thereofI as hereinafter described and claimed.

In the accon'ipanying drawings-Figure 1 is a perspective view of a plow beam constructed in accordance with my invent-ion, looking from the front end thereof. Fig. 2

is a similar view of the same looking from the rear end thereof, and showing the bottom side of the beam. Fig. 3 is a vertical transverse sectional view of the beam, also showing a standard attached to the beam and a brace for the standard.

y improved hollow metallic plow beam 1 is cast in a single piece. rlhe beam is rectangular in shape, cross sectionally, and comprises a top 3 having a downwardly and forwardly inclined front portion et, vertical sides 2, a bottom and a. front wall 7 closing the front end of the beam, the rear end. of the beam being open. On the top of the beam at a suitable distance from the rear end thereof, are a series of transversely eX- tending rack teeth 15. The bottom comprises the integral front portion 5 and the integral rear portion 6, that portion of the bottom between the parts 5 and 6 being open, as shown in Figs. 2 and 3, to lighten the construction of the beam. The front bottom portion 5 coacts with the side walls and the front wall T to strengthen the construction of the front end of the beam. rllhe front end of the beam has an opening 8 to receive the stud of a clevis, and openings S) are in the upper side of the. beam and the bottom portion 5 thereof to receive a bolt which is employed to secure the upper and lower arms of the clevis respectively on the upper and lower sides of the beam. ln the sides of the beam at a suitable distance from the rear end thereof, are openings l1 to receive a bolt employed for securing the forked upper end ot' a standard to the beam. lVhen a standard. comprising a. pair of members 23 is used in connection with the beam, the said members bear on opposite sides of the beam and are secured thereto by bolts 26, tbe bolt 25 engaging one of the teeth 15 on the upper side of the beam, and the bolt, 2G bearing against the bottom of the beam. The lower ends of these members 23 are connected together by a block Q4, which is bolted thereto, and the said standard is provided with a brace Q8, the lower end of which is secured between the members 23, by a bolt 27, the upper end of the standard bearing against the integral portion (i, constituting the rear part of the bottom of th-e beam, the Said portion t3 of the beam having an opening 10 for the reception of a bolt to secure the rear end of the brace in place, the upper lside of the beam near its rear end also having an opening 10 for the upper part of the said bolt.

.Transverse openings 12 are in the sides of the beam near its rear end to receive a bolt for securing the brace of another form of standard to the beam. In the o pposite sides of the beam near the rear end thereof, are inclined grooves 13 to receive the lower ends of a pair of handle bars, and are provided with openings 14, for the reception of bolts to secure the handle bars in place.

It will be understood that the integral rear portion 6 of the bottom of the beam connects the sides 2 of the beam at the point where the said grooves are located, and strengthens the beam at that point, and serves to preventthe weakening of the beam by the provision of the grooves.

My improved beam is light, may be easily cast and may be manufactured at minimum cost.

Having thus described the inventiomwhat l tion of the bottom ot the beam connecting 15 is claimed is:

As a new article ot' manufacture, the herein described cast metal hollow plow beam comprising a top, sides, a bottom7 and a closed front end, the bottom havingan opening extending nearly from end to end thereof, the top of the beam being formed at a suitable distance from its rear end with a series of transverse rack teeth, the sides of ythe beam being formed at a point between the rack teeth and the rear end of the beam with inclined grooves to receive the lower ends of the handle bars, the integral rear porthe sides of the beam at the point where the said grooves are located, and strengthening the said grooved portion of the beam, the integral front portion of the bottom of the beam coacting' with the wall which closes the front end of the beam to strengthen the construction thereof.

In testimony whereof I hereunto afiX my signature in the presence of two witnesses.
